The Libyan government has declared an immediate ceasefire intended to protect civilians, after the UN Security Council voted on a resolution to use “all necessary measures” to protect civilians in Libya. UN Security Council Resolution 1973 authorizes taking military action, which could include bombing Col Gaddafi’s forces on the ground if necessary. Libyan Foreign Minister Mussa Kussa said Libya, as a member of the UN, was “obliged to accept the UN Security Council’s resolutions”, the BBC reports. Western powers have been deliberating further action in Libya as pro-government forces began advancing on the rebel stronghold of Benghazi.
